. GATJAGHER,

a citizen ot the United States, residing'at lvashington, District of Columbia, have invented certain new unduseful Improvements in Battery Handliamps; hereby declare the following to and l do he a full,

clear, and exact description ot the invenu tion, such as will enable others skilled in the art to which it'appertains use the same.

This invention in lates particularly to to make and battery hand lampsrearrangements for sup* portingr within the metallic. case. of a lamp a conducting strip which between the switch mechanism the side of the case and front' end ort the case.

completes the circuit mounted on the reflector at the The usual arrangement for completing the circuit; consists ot a metal strip the inner Vface of the case moved into reilector which is suitably case upon theend so that the circuit will be compl the reflector only when the is advanced intoengagement ,.tlector, In a hand it is customary at the present vide a switch of the so called that is a switch comprising a autoi'na'tically returns to open of a hand lamp havingr lamp havingH a metal case slidably `mounted on and adapted to be or out ot engagement` with the insulated from the ot which' it is supported,

be attached case, andl no the conductor need be When a switch of the dual type is applied to a. metal case lamp it is insulate from the case circuit between the switch and necessary to thetixed conducting strip which is required for completing,r the the reflector.

It is an object ot' this invention to provide an arrangement for this consist of a comparative y Sina iurposc which shall ll number of parts, all of which may be quickly assembled within the case which need only be modified in a few particulars to adapt it to receive the strip and its associated insulation.

In accordance with the invention a number ot' pairs olf parallel cuts are made in the case transverse to its axis, and the met-al between the cuts is indented to l`orm depressed straps, which, in conjunctionv with the porvtions ot the case adjacent to the straps, form B5 a channel extending longitudinally of the case. and adapted to receive the conducting strip which wrapped with non-conducting material, such as paper or the. like, to insulate it `from the adjacent port-ions ol the 'I0 pressed into circuit closing position, as by and held by its used in connection with being loi'med with an offset portion project-I 85 ing' into the switch housing, or by being pro' vided with a stud or rivet which extends into the housing, the case being cutaway to allow lor the passage ol. such ollset portion u or stud. I

The particular nature ot the invention, as well as other objects and advantages thereol", will appearniore clearly from a description of certain preferred embodiments as shown in the accompanying which;

Figure l shows a hand lamp with onel form of conducting strip applied thereto;

Fig. 2 is an enlarged view in longitudinal drawings',l in 95 section of the strip and the switch associated therewith Fig, 3 is hand lamp;

Fi It is an enlarged sectional view along the line 4,4 of Fig. 3; and Fig. 5 is a detail view showing a modified form of strip.

The metal case hand lamps towhich the invention may be applied may be of any construction. For the purpose of illustration a view Vof the interior of the switch mechanism mounted on the exterior of the case, a conducting member extend ing between the switch mechanism and the reflector, said member being surrounded by insulating material and held in fixed position within the case by members formed out of the material thereof.

2. In a battery hand lamp comprising a case having a battery therein, a reflector mounted upon one end of the case and switch mechanism mounted'on the exterior of the case, a conducting member surrounded by insulating material extending between the switch mechanism and the reflectorand held in fixed position within the case by members formed out of the material thereof, said member being provided with an offset portion extending through an aperture in the case, and adapted to be engaged by a movable part of the switch mechanism.

3. In a battery hand lamp comprising a case having a battery therein, a reflector mounted upon one end of the case and switch mechanism mounted on the exterior of the case, a conducting member extending between the switch mechanism andthe reflector, said member being surrounded by insulating material and held in fixed position within the case by indented transverse stl'np like portions of the material of the case.

4. In a battery hand lamp the combination of a case provided with indented portions extending transversely thereof, a conducting member held` in place betweenthe indented portions and the innersurface of the case, insulating m'aterial between the conducting member and the adjacent sur.-

faces of the case and' the indented portions, a reflector mounted at one end of the, case and engaged by one end of the conducting member, and switch mechanism mounted on the case and provided with a part adapted to be broughtinto engagement with the con-4 ducting member. f

5. In a battery hand lam-p the combination of a case provided with indented portions extending transversely thereof, a conducting member held in place between the indented portions and the inner surface of the case, and provided with an offset portion projecting through an aperture in the case, insulating material between the conducting Inember and' the adjacent surfaces of the case and the indented portions, a reflector mounted atvone end of the case and engaged by one end of the conducting member, and switch mechanism mounted on the case and provided with a part adapted to be brought into engagement with the oilset portion of the conducting meniber.

6. In a battery hand lamp the combination of a case provided with indented portions extending transversely thereof, a conducting member held in place between the indented portions and the inner surface of the case, insulating material surrounding the conducting member to keep it out of electrical contact with the adjacent surfaces of the case and the indented portions, a reflector mounted at one end of the case and engaged by one end of the conducting member, and switch mechanism mounted on the case and provided with a part adapted to be brought into engagement with the conducting member.

7. In a battery hand lamp the combination of a conducting member surrounded by a wrapper of insulating material, a case provided with depressed portions constituting in connection with the adjacent portions of the case a channel within which the conducting member and its wrapper are held by frictional engagement,l a reflector mounted at one end of the case and engaged by one end of the conducting member, and switch mechanism mounted on the case and provided with a part adapted to be brought into engagement with the conducting member.

8. In a-batter hand lamp comprising a case having a attery therein, an incandescent bulb at one end of the case and switch mechanism mounted onthe exterior of the case, a conducting member for completing circuit between the bulb and the switch mechanism, said member being surrounded by insulating material and held in fixed position within the case by members formed out of the material thereof.

9..- In 'a batte hand lampcomprising a case having a attery therein, 4an incandescent'bulb at one end o, the case and switch mechanism mounted on the' exterior of the case, a conducting member, surrounded by insulating material, for completing circuit between the bulb and the switch mechanism, and held in fixed position withv in the case by members formed out of'the material thereof, said member-being provided .with an offset portion extending through :an 'aperture in the case, and adapted to be engaged by a movable part of the switch mechanism. n

l0. In a battery hand lamp the combina tion of a case provided with indented por-l switch mechanism mounted on the case and provided with a part adapted to be brought into engagement with the offset portion of the conducting member.

In testimony whereof I aiix my signature.
